BP7B – L-Series IPM Interface Circuit Reference Design
Description: The BP7B is a complete isolated interface circuit for six and seven pack low and medium power L-
Series IPMs. This circuit features the VLA606-01R opto-interface IC for isolation of control signals and isolated
power supplies for the IPM’s built-in gate drive and protection circuits. The isolated interface helps to simplify
prototype development and minimize design time by allowing direct connection of the IPM to logic level control
circuits.
Features:
• Complete three-phase isolated interface circuit with
brake control and fault feedback
• 2500VRMS isolation for control power and signals
• Standard AMP MTA .100” Input Signal and Control
Power Connectors
• Operates from a single 24VDC supply
• Compact Size 4.0” x 2.5” (63mm x 102mm)
Applications:
BP7B is designed for use with Powerex L-Series six
and seven pack IPMs: 50A-300A 600V and 25A-
150A 1200V.
¾ Use Powerex VLA106-24151 and VLA106-
24154 DC to DC converters for isolated
control power. See Table 1 for
requirements.
Ordering Information: BP7B-LS is a kit containing a bare PCB with one VLA606-01R and four VLA106-24151
DC to DC converters
(For use with L-Series IPMs in package A and B)
BP7B-LB is a kit containing a bare PCB with one VLA606-01R opto-interface IC, three
VLA106-24151 DC to DC converters and one VLA106-24154 DC to DC converter
(For use with L-Series IPMs in package C)
BP7B is a bare PCB only.
Note: User must supply Optocouplers and passive components to fully populate the BP7B (See Table 2)
